The choice between nitrogen and regular old air is not as cut-and-dry as it may seem. Experts have been arguing about this for years. While we believe that nitrogen is the better option, there are valid points on both sides of the debate.

So, that means that you have to determine one thing — is nitrogen better than air? What’s the best option for your tires? Many people will argue that nitrogen has some scientific advantages over air, but let’s look at the arguments’ factors to see if we can help you determine which is right for you.
Nitrogen vs. Air: What’s The Difference?
The difference between air and oxygen is the amount of nitrogen. Air contains 78 percent nitrogen, while oxygen only makes up 21 percent. Nitrogen makes up 99 percent of pure nitrogen, which is why you should be filling your tires with that gas — it’s the most efficient way to keep them perfectly inflated.
Nitrogen: Pros and Cons
Nitrogen tire inflation is becoming the new standard in America — and for a good reason. While the air may be an excellent way to fill up your tires, nitrogen is even better. It has many advantages that are especially important to heavy-duty drivers, such as truckers and people with larger cars who use their vehicles for commuting, hunting, or often just driving around town.
Reduces the risk of oxidation
Nitrogen in tires inhibits oxidation. Rainy snowy weather results in increased water on the road, leading to more oxidized tires and less grip. But with nitrogen-filled wheels, rubber stays pliable even when it’s wet.
Nitrogen is the green alternative
It will be more environmentally friendly for the world if nitrogen-filled tires become more popular. Nitrogen maintains proper pressure, which means you can achieve better gas mileage and reduce emissions. Better tire performance means less tire manufacturing, which will, in turn, reduce the use of natural resources.
A nitrogen-filled tire has the advantage of holding up to three times more pressure than a regular air-filled tire. Because nitrogen molecules are slower and more extensive than air molecules, they don’t escape from the tire as quickly. This means that you can keep your tire at the proper pressure for longer, helping you to save on gas and reduce wear and tear on your tire — and ultimately providing better gas mileage.
Not all gas stations have nitrogen generators, so this can be a considerable inconvenience.
What about the regular old air?
Inflating tires with air is a fast and convenient method that has been around for decades. It used to be the only way that people could get their tires inflated — although it’s now possible to pump your tires with nitrogen, compressed air is still easier to find. The problem with using air is that it eventually seeps out of your tire, while nitrogen stays in place for more extended periods.
Conclusion: Is nitrogen worth it?
While compressed air might seem like a viable method for filling your tires, nitrogen is even better. Nitrogen can help prevent tire pressure drops over time, and it can improve the overall safety of your vehicles.
